net: phy: re-design phy_modes to be self-contained
of_get_phy_mode() uses a local array to map phy_interface_t values from include/linux/net/phy.h to a string which is read from the 'phy-mode' or 'phy-connection-type' property. In preparation for exposing the PHY interface mode through sysfs, perform the following: - mode phy_modes from drivers/of/of_net.c to include/linux/phy.h such that it is right below the phy_interface_t enum - make it a static inline function returning the string such that we can use it by just including include/linux/net/phy.h - add a PHY_INTERFACE_MODE_MAX enum value to guard the iteration in of_get_phy_mode() Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
